Water

Water is a key natural resource supporting the life of most organisms on the planet.

It covers over 70% of its surface. Water is irreplaceable as a staple for consumption, the most basic hygiene product, and a recreational asset, and also a prerequisite for the development of economy − be it through agriculture, manufacturing or transport.

Protection of water consists of examining and assessing its quality and taking technical, organisational and legal measures to preserve or restore the quality of natural water resources, and protect the national hydro-economic balance.

Plock Production Plant

At the Płock Production Plant, water is used in manufacturing processes, but is also a feedstock for the production of steam at the CHP plant. The Plant’s natural supply of water is the Wisła river, and drinking water is drawn from deep water wells. Depending on the requirements of each unit, the following types of water are abstracted:

  • Utility and fire-fighting water;
  • Decarbonised water;
  • Softened and deaerated water;
  • Demineralised water;
  • Drinking water; or
  • Circulating water.

The amount of water the Plant is allowed to abstract is specified in a decision issued by the relevant authorities. PKN ORLEN holds a separate water use permit for surface and underground water abstraction, valid for the entire Płock Production Plant. Under the permit, the Company monitors the volume and quality of swater abtracted.

Water abstraction by the Płock Production Plant by volume and water type

ParameterYearIncrease/decrease 2013/2014
20132014[%]
Water abstracted from the Wisła River [m3] 22,259,568 22,198,773 - 0.3
Water abstracted from deep water wells [m3] 487,016 421,825 - 13.4
Amount of recycled water [m3] 2,919,225 3,260,477 11.7

The 11.7% growth in the amount of recycled water in 2014 was driven by the Plant’s increased demand for utility and fire-fighting water, with the year-on-year increase attributable to scheduled maintenance shutdowns of the production installations. Bleedback of water from water units to utility and fire-fighting systems was up 21.7% year on year as a result of the construction and launch of boiler blowdown pump systems at the BWR1 and BWR3 units. In 2013, blowdown from these units was fed directly to the wastewater system. Blowdown water from water units directed to utility and fire-fighting systems currently accounts for 30% of its total production for the Płock Production Plant.

The Company pays particular attention to the protection of natural resources across all areas of its operations. The same is true for water resources, which are always used in a prudent manner.

For instance, the Company has introduced a system for recycling wastewater as industrial water. The process consists in looping the water and wastewater systems, converting wastewater into industrial water (tertiary treatment − coagulation and flocculation accelerators, and quaternary treatment − algae and reed ponds), and using an inhibitor node, in which treated wastewater is inhibited and sanitised by chlorine water. Treated wastewater is used as utility water for washing, cleaning and fire-fighting applications. To make the water fit for feeding into utility and fire-fighting systems, the plants are controlled for cleanliness during leakproof testing. Water carried to the utility and fire-fighting systems is also sourced from blowdown of circuits. Condensate from steam circuits is treated and used as high-quality water.

Because the Plant uses substantial quantities of water, it recycles as much of it as possible for further use.

Włocławek PTA Plant

The water consumed by the Włocławek PTA Plant for its operational purposes is delivered by ANWIL S.A., an external supplier.

Demineralised water [m3] 1,985,491 1,937,141 -2
Industrial water [m3] 84,278 65,140 -23

Sanitary and drinking water [m3] 5,061 6,749 33
TOTAL – Water delivered by ANWIL S.A. [m3] 4,172,217 4,031,734 -3

In 2014, the company reported a year-on-year decrease in industrial water consumption as a result of fewer ad-hoc cleaning operations (service points), which is attributable mostly to the staff’s greater experience and improved work culture.

The higher consumption of sanitary and drinking water was related to periodic testing of emergency shower units.

The data for 2013 and 2014 account for 36 Group companies, including PKN ORLEN S.A. The difference between the size of the impact in 2012 and 2013 is attributable to inclusion of new data, i.e. adding Energomedia Sp. z o.o. and Spolana a.s. to 34 Group companies.
